Cerebral Palsy maybe/maybe not

somewhat. Even so, we still don't call it quadriplegia.

The peculiar pattern and quality of muscular usage is what is important. PVL or "diplegia" conveys that. So diplegia - forget that di means two - may well have four limbs involved. The dominant manifestation is legs AND in a certain way. There is a unique quality to the way diplegia function is impaired. Lately, even parents are referring to their children as having PVL rather than diplegia. Good. That tosses out the old misleading nomenclature. I like that. PVL is a very common neurological complication in preemies. One third of all CP is prematurity related and thus have the PVL type of neurological based involvement. The classic look of spastic diplegia (PVL) is inward rotation crouch. The typical functional limitation is via speed related recruitment of unasked for muscular activation (speed related recruitment of additional muscle activity is called spasticity). Anything else which is called spasticity is called that WRONGLY!!!! It is an important distinction. Kids with high levels of spasticity may have their control mechanisms totally intact, but, overloaded by extraneous stuff. Sensory mechanisms are usually working. Remember that prematurity is, itself, a complication of something else. There can be incompetent cervix or twin / triplet issues. Prematurity may be brought on by genetic problems within the child's genome causing late spontaneous abortion. The earlier the prematurity, the more likely an underlying embryological or fetal cause is also present.

Nit picking? No. Don't get blinded by statistics. Statistics do not cause. They report.
